Power amplifier is the part of sound electronics. It is designed to maximize the magnitude of the power of given input signal. In sound electronics, the operational amplifier increases the voltage of ...

A transistor amplifier circuit is an electronic circuit that uses one or more transistors to amplify an input signal. The basic operation of a transistor amplifier circuit involves using a small input ...

Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

There are many different audio power amplifier ICs to choose from, but designing an audio power amplifier using an operational amplifier (op-amp) and bipolar transistors is quite advantageous.

This single transistor audio mixer is used in an amplifier circuit design with base driven transistor and with its emitter being current controlled, most of the driving current flows through the ...

In the measurement industry, a very crucial functional block is a Programmable Gain Amplifier (PGA). If you are an electronic enthusiast or a college student, you have probably seen a multimeter or ...

If you open up the perennial favourite electronics textbook The Art Of Electronics and turn to the section on transistors, you will see a little cartoon. A transistor is shown as a room in which ...

We’ve previously remarked upon a generation lucky enough to be well-versed in microcontrollers and computersised electronics through being brought up on the Arduino or the Raspberry Pi but unlucky ...
